TYPEWRITING MACHINE.

Application filed May 1G, 1921i. Serial No. 463,257.

To all 107mm t may concern:

Be it lnown that I, BURN-IAM C. STICK- Nn 7, a citizen of the United States, residing in Elizabeth, inv the county of Union and 5v State of New Jersey, have invented certain new and useful improvements in Typewriting- Machinesl of which the following; is a specification.

rlhis invention relates to sound-deadening hoods for typewriting machines, and of the same Vgeneral type disclosed in my eopending application, Serial No. 429,61?, tile(Y December l0,` 1920 (now Patent No. 1,519,224, dated Deeember 16, w24).

The invention comprises, in combi ation vwith a typewrting machine haviingr Jfeatures (3o-operating` therewith, a sound-deadening casing or hood for enclosing the noisesprodueingr parts of the machine, while the keys and other parts of the machine used in its operation project from the hood.

The invention provides for alongitudinal slot at the front between a lower body part and an upper, rearwardly swingable, hin red l cover part or dome, beneath which a pluralit of linger-pieces mayproject from the usual carriage, which in the present invention, may be mountedlto travel within the cover part between the endwalls thereof. :in It is one feature of the present invention to provide an improved means for maintaining' the slot in closed' condition, sueh means comprising a pair of cooperating easily yielding` cushion-strips, one of which is mounted on the lower body part just below the slot, the other of which is mounted on the coverpart just above the slot, and a light resilient reinforcing means within said strips7 whereby the strips offer praet" 'ally no i" resistance to the passage of the levers alone' the slot, and therefore to the movement of Vthe carriage. Said reinforcing' means will 1 restore the'contaet between the strips after the latter have been separated by the passage l5. or operation of the finger-pieces progeeting througlithe slot.

Another feature of this invention is the pro-vision of means for transmitting the sound of the line-end bell-signal to the eX- terior of the sounddeadening casing, said signal being' ordinarily mounted on the enclosed portion of the type/writingr inadiine. For this purpose, a souinl-transitiittinetube is mounted adjacent. the signal, and is erttended forwardly to a point adjacent the` type-keys, which exi end outside of' the casing'.

Another feature of the inventifm is the provision of a detachable front for the lower body part of the sound-deadoning' hood. which enables the hood to be more readily applied to a machine and the lower body part to be readily assembled, and fasten ing means for said detachable front, said fasteningmeans lying wholly within the casing.

Another feature of this invention is the pro iision of an eflicient linkage between the cover and lower body parts of the hood, which necessitates a minimum of foree for raisingV the cover when desired.

Still another feature of this invention is the provision of an upwardly and downwardlyextending finger-piece at the forward end of a line-space lever, which enables the latter to he easily and readily operated.

Other features and advantages will here inafter appear` In the aCCompanyineY drawings,

Figure l is a perspective view of the hood applied to an Underwood standard type- 'writing machine as modified by the invention, the front plate and the lower body part having been removed.

Figure 2 is a perspective viev-f. from the rear, of the front plate of the lov-:er body part detached from the hood.

Figure 3 is a vertical sertion througil. tirx hood and machine` Figure lis a plan view ol' ihr device shown in Figure Il, the hinged rover ol' thi hood havingv been removed to expose the` underlying' mechanism.

The lhiderwood standard tv'wvcritiin): machine comprises a main frame l() and an extension ll of said frame. within which extension are positioned baule; of keys l2 fixed to the ends of key-levers lil, which oieral'e bell-eranks lll to swing' the typebars l5 upwardly and rearwardly to strike against a platen 16. Said platen is fixed upon a shaft 17 vjournaled in the end walls 18 of a platen-frame 19 forming part of the usual carriage 20, which rides upon front and rear rails 21 and 22 on the main frame of the machine. The platen may be rotated by the usual finger-wheels 25 fixed to the endsl of shaft 17 oi' by the usual linespace mechanism, of which line-space handle 26 and slide 27 are shown. The carriage is fed at line-space intervals to the left by an escapement mechanism (not shown), which operates a pinion 30 in engagement with a rack 31 at theend of a levei 32, said lever projecting forwar lly to forni the usual carriage-release lever, to be described more fully hereinafter. A finger-piece 35 is detachably mounted on the front bar 36 of the carriage for Yreturningthe latter to the right, and is secured in place by clamping means comprising a plate 28 and screws 28a, Figure 3, the clamp plate 2S having a rib 29 engaging under the finger-piece The clamp plate may be provided witha lateral extension 40 having vertical guides 41 for guiding a forward extension or finger-piece 42, detachably mounted on the carriage-release lever 32, by means of a clamp plate 42a ven ,'z.ging a lateral extension 32 of the release lever 32, the clamp plate 42a being secured by a. screw 42"; lt will be understood'that the guides 41 prevent displacement of the finger-piece 42 onY the lever 32 which might otherwise be caused by a force acting sidewise on the finger-piece 42. The structure of theV linespace handle 26, finger-piece 35 and extension 42 willrbe more fully described hereinafter, in connection with the structure of the sound-deadening hood. provided with the usual pointer 37 co-op- @rating with a scale 38 fixed to the main frame of the machine.

' The typewriting machine rests upon a sound-deadening base-plate which forms Va bottom plate for the sound-deadening casing or hood, the latter comprising a lower 'or body portion 51 and an upper or cover portion 5.2. The body portion 51 comprises "a front wall 53, end walls 54, and a` rear wall 55, the jfront wall being provided with Y an openinglarge enough to receive the main typewriter 'traine 10. 'lhe'frfnit and side "walls'extend upwardly to a point below the bottom surface of the platen, the rear wall extending upwardly a greater distance, and the side walls being provided with horizontal extensions 56 at their upper ends extending to pointsbeyond the ends of the carriage in the left and right limiting positions thereof.V Vertical flanges 60 onV the Yends ofthe extensions 56 meet extensions 61 of the front. wall and `corresponding extensions V,of the' rear wall to form an upper container in which the carriage travels to The carriage is i the right and left. The covei 52 is hingedly connected by a rear wall 63 to the rear wall 55 at 62, and comprises also side walls 64 co-operating with Vfianges 60, a forwardlying replacement, and occupying substantially the entire top wall, thus rendering visible the typing on work-sheets around the platen. The various Vparts of the body part and cover part of the casing heretofore described are held together in any well-known inanner, as, for instance, by angle-irons 69.A

Vlt will be apparent that the 'front wall 53 of the body part terminates at its top a distance considerably below the lower edge 71 of the froiitrwall 66 of the cover part, Ythus leaving a large opening lengthwise of the machine. vided a front cover-plate 72 shaped like the front wall 53, but extending upwardly a greater distance. The upper edge 73 ofthe There is further procover-plate does not reach the lower edge 71 of the front wall .66, thus leaving a slot 8Ol for a purpose to be hereinafter described., said slot being closed ,to prevent escape of sound, in a manner which will also be described hereinafter. rhe front. cover-plate isreadily attached to the front wall 53 by Vwithin the casing. By merely withdrawing the bolts 74the front cover-plate may be removed and the machine withdrawn from the casing. To assist in positioning the front plate 72 when attaching the latter,

containers or troughs 53 are provided at the lower ends of the front wall 53, into which the lower ends 57 Vof the cover-plate 72 may be set, the upper edgeof said plate being first introduced behind a finger-piece of the line-space handle 26. The front plate may be located laterally by portions 58 which close the outer ends of the troughs 5S land engage the outer edges of the end-i 57 of the plate 72. To facilitate manipulation of the front plate 72, it may be pro-` vided with finger-pieces 72a. lt should be lll() the interior o-f the machine to the exterior of the hood is through the'v comb 110 at the frontof the machine in which the type-bars operate. Means are therefore provided for carrying the sound of the bell 111a forwardly tothe comb 110, said means comprising a tube or horn 111 terminating at the bell and having a forward extension 112 adjacent one side of the mainframe 10, said extension having a bent portion v113 adjacent the yfrontV of the machine. "The bell-signal is usually located not only to the rear of the comb but above it, and, to bring the tube 111 I tothe comb, it is therefore necessaryt'o di- I `porting rect it downwardly between the type-bars, and, for this purpose, a tube 114 is inserted upwardly between the outer key-lever 13 and the usual back-space key-lever l12() and is connected to tube 111 at its upper edge, preferably by a hook 115 on portion 113 engaging in a slot 116 at the upper end of tube 114,`and is securedto the tube 111 by a screw 117 which passes through an ear 118 on the portion 113, the screw being threaded into the wall of the tube 114. The tube 111 may be disposed in the usual opening 121 in the left-hand side of the. frame and is provided Vwith a slot 121g, so that it may be readily slippedbehind the usual bell-supbracket 122 and straddle the bellholding screw 123. Tfo facilitate the manipulation of the screw 123, the right-hand wall of the tube 111 is provided with a hole 12-1 through which a screw-driver may be inserted from the right-hand side of the ma-r chine. VThe .following claims are limited to inventive organizations that areV not disclosed in my co-pending application, No.
